Happy repeat customer!
All of the products have massively exceeded expectations. I haven't had any GI issues with the gels, even at 90g of carbs/hour. Furthermore, the combination of flavour + consistency makes them super easy to take!
The chews have been a real surprise winner and are great to mix things up on long runs.

11/10 would recommend
I've loved every product I've tried - especially the 30g gels. I have a sensitive stomach, but I've never had any issues with these. The taste (subtle, but nice), texture (thick enough not to make a mess), and packaging (convenient) are 11/10!

Getting use to nutrition through training and by far the best. The nutritional planner made it easy to understand my needs and streamlined the journey.

If you want the most of your training you need to try PF
Honestly, PF is next level. Their products are great, their entire system stacks so well together, and what's even better is their service. Their help in building a fueling plan was so educational, and has made a big impact to my performance on the bike.

All round brilliant service.
Really like the whole service. The advice on which products to get was very helpful, especially for someone new to having to fuel runs. The products arrived super quickly. The electrolyte tablets were easy to use and tasted good. The chews are a good alternative to gels. I quite look forward to breaking my long runs up with a chew.
